, chimney.l It isulsoryellknownthatthe smoke in cities where soft coal is burned is not duev pense withthe expensive, high,'and unsightly 'v smokestaieks now in use, for by using our auxiliary. stack there is sufficient draft obtained, and, as the products of combustion are burned, there s novnecessity for carrying the smoke-stack above the roofs of houses. The' height of chimneys een also be reduced, and the stack placed on the chimney near the roof7 andscan be mede ornamental when desired.

The smoke-consu1ners in general use cannot be used upon or with the ordinary houseto' munufactories, but to dwelling-houses. Therefore by usingva device of this kind agrcat portion of such smoke `is obviated. Where.; coal-gas is conveuicnt,wewill preferably carry up pipes and burners into the auxiliary stack. 1 We can then light the burners by electriclighting apparatus, and turn the gas on' and off from convenient point at ory near the ground. l

Having thus described our iuventonfwhatv we claim as nemend desire to secure by Letters Pat-ent, .is-

upon a chimney or smoke-stack and coinmingling the products of combustion with atmospheric nir ns they are emitted from the top ,of thcvcliiinney or stack, and then bringing `said oxygenized products into contact with a 1. The method of consuming smoke, which consists in placing agi auxiliary smoke-stack v inlet'iubes and lumps or iiainesentering seid sta/ck, substnntinlly :is set forth. l
